DETAILED DESCRIPTION

Reference will be made in detail to embodiments of the present disclosure. The embodiments shall not be construed to limit the present disclosure. The same or similar elements and the elements having same or similar functions are denoted by like reference numerals throughout the descriptions. The embodiments described herein with reference to drawings are explanatory, illustrative, and used to generally understand the present disclosure.

In the prior art, when control of the smart device is desired, a wake-up word is required to wake up a smart device and then the smart device is controlled according to a control instruction, which brings complex operations and bad user experience. In order to solve the problems in the prior art, embodiments of the present disclosure provide a method for controlling a smart device.

With the method for controlling a smart device according to embodiments of the present disclosure, after the speech recognition is performed on the speech signal acquired by the smart device, when the control instruction corresponding to the speech signal matches with the present operation scene of the smart device, the operation state of the smart device is adjusted according to the control instruction. In this way, the smart device can be controlled according to the control instruction matching with the present operation scene without any wake-up words, such that the control method is simple and flexibility of the control method is improved, thus improving the user experience.

A method for controlling a smart device, an apparatus for controlling a smart device and a computer device according to embodiments of the present disclosure will be described in detail hereinafter with reference to accompanying drawings.

FIG. 1 is a flow chart illustrating a method for controlling a smart device according to an embodiment of the present disclosure.

As illustrated in FIG. 1, the method may include the followings.

At block 101, speech recognition is performed on a speech signal acquired by the smart device, it is determined whether a control instruction corresponding to the speech signal matches with a present operation scene of the smart device.

At block 102, when the control instruction matches with the present operation scene, an operation state of the smart device is adjusted according to the control instruction.

The method for controlling the smart device according to the embodiments of the present disclosure can be executed by an apparatus for controlling the smart device according to embodiments of the present disclosure. The apparatus for controlling the smart device can be disposed in a smart device such as a loudspeaker box, a phone, a computer, or can be disposed in a server for controlling the smart device such as the loudspeaker box, so as to control the smart device.

In detail, a speech input means such as microphone can be provided in the smart device in advance, such that when the user controls the smart device via speech, the smart device can acquire the speech signal via the speech input means.

Additionally, a speech recognition module can be provided in the apparatus for controlling the smart device, such that after the smart device acquires the speech signal, the speech recognition module can be used to perform speech recognition on the speech signal, so as to acquire the control instruction corresponding to the speech signal.

It can be understood that, before determining whether the control instruction corresponding to the speech signal matches with the present operation scene of the smart device, the present operation scene is determined. Before the block 101, the method may further include: determining the present operation scene and acquiring a set of control instructions matching with the present operation scene.

In detail, a mapping relation between the operation scenes of the smart device and sets of control instructions can be preset, such that after the present operation scene of the smart device is determined, the set of control instructions matching with the present operation scene can be acquired according to the preset mapping relation. Then it is determined whether the acquired control instruction is contained in the set of control instructions matching with the present operation scene, if yes, the operation state of the smart device can be adjusted according to the acquired control instruction, if no, the control instruction is discarded and no adjustment on the operation state of the smart device is performed.

For example, when the operation scene of the smart device is playing music, the corresponding set of control instructions which is set in advance includes control striations such as “next”, “last”, “turn down the volume”, “pause”, “change another song”, “hot songs” or the like. When the operation scene of the smart device is playing music, the corresponding set of control instructions includes control instructions such as “financial report”, “evening news”. “morning news”, “Beijing News”, “overseas news” or the like. Then, assuming that the present operation scene of the smart device is playing music, when the control instruction corresponding to the speech signal acquired by the smart device is “pause” which is contained in the set of control instructions corresponding to the scene of playing music, the playing of music in the smart device can be paused according to the control instruction “pause”; when the control instruction corresponding to the speech signal acquired by the smart device is “morning news” which is not contained in the set of control instructions corresponding to the scene of playing music, the control instruction is discarded and the operation state of the smart device is not adjusted.

It can be understood that, in prior art, when the control of the smart device is desired, the wake-up word is required to wake up the smart device and then the smart device is controlled according to the control instruction. For example, the preset wake-up word may be “xiaodu”, the user needs to pronounce “xiaodu” first and then pronounces the control instruction such as “last”, “morning news” or the like, so as to control the smart device. However, with the method provided in the embodiments of the present disclosure, the user needs not to pronounce “xiaodu” or any other wake-up words, and controls the smart device according to the control instruction matching with the present operation scene, which is easy to implement and improves the flexibility, thus improving the user experience.

It should be noted that, in practice, when the control instruction corresponding to the speech signal does not match with the present operation scene of the smart device, the present operation scene of the smart device may be not influenced by performing the control instruction. For example, when the smart device is playing music, if the control instruction “setting an alarm clock at 3 o'clock pm”, the alarm clock can be set in background, which does not influence the playing of music.

Accordingly, in an implementation of the present disclosure, when the control instruction corresponding to the speech signal does not match with the present operation scene of the smart device, it is determined whether to perform the control instruction according to demands.

After the block 101, the method may further include: when the control instruction corresponding to the speech signal does not match with the present operation scene of the smart device, determining whether the control instruction collides with the present operation scene of the smart device, if yes discarding the control instruction, if no performing the control instruction.

In detail, it can be determined whether the control instruction collides with the present operation scene of the smart device in many ways.

For example, it can be determined whether the control instruction needs to be performed in background or foreground, when the control instruction needs to be performed in the foreground, it can be determined that the control instruction collides with the present operation scene of the smart device, and the control instruction is discarded. When the control instruction needs to be performed in the background, it can be determined that the control instruction does not collide with the present operation scene of the smart device, and the control instruction is performed.

In another embodiment, it can be determined whether resource to be occupied by the control instruction is the same as resource occupied in the present operation scene, if yes, it can be determined that the control instruction collides with the present operation scene of the smart device, and the control instruction is discarded, if no, it can be determined that the control instruction does not collide with the present operation scene of the smart device, and the control instruction is performed.

For example, when the operation scene of the smart device is playing music, the corresponding set of control instructions which is set in advance includes control striations such as “next”, “last”, “turn down the volume”, “pause”, “change another song”, “hot songs” or the like. When the operation scene of the smart device is playing music, the corresponding set of control instructions includes control instructions such as “financial report”, “evening news”, “morning news”, “Beijing News”, “overseas news” or the like.

Assuming that the smart device is playing music, when the control instruction “morning news” is acquired, it can be determined that the control instruction “morning news” collides with the present operation scene of the smart device and the control instruction is discarded since the control instruction “morning news” does not match with the present operation scene and both operations of broadcasting the morning news and playing the music occupy a speaker of the smart device; when the control instruction “setting an alarm clock at 3 o'clock pm” is acquired, although the control instruction “setting an alarm clock at 3 o'clock pm” does not match with the present operation scene, the setting of the alarm clock can be performed in background without influencing the playing of music, such that the control instruction “setting an alarm clock at 3 o'clock pm” does not collide with the present operation scene of the smart device and the control instruction is performed.

With the method for controlling a smart device according to embodiments of the present disclosure, after the speech recognition is performed on the speech signal acquired by the smart device, when the control instruction corresponding to the speech signal matches with the present operation scene of the smart device, the operation state of the smart device is adjusted according to the control instruction. In this way, the smart device can be controlled according to the control instruction matching with the present operation scene without any wake-up words, such that the control method is simple and flexibility of the control method is improved, thus improving the user experience.

In summary, after the speech recognition is performed on the speech signal acquired by the smart device, when the control instruction corresponding to the speech signal matches with the present operation scene of the smart device, the smart device can be controlled without a wake-up word. In practice, the smart device can be controlled according to whether the preset key word is contained in the speech signal, which can be described in detail with reference to FIG. 2.

FIG. 2 is a flow chart illustrating a method for controlling a smart device according to another embodiment of the present disclosure.

As illustrated in FIG. 2, the method may include the followings.

At block 201, speech recognition is performed on a speech signal acquired by the smart device.

Regarding the implementation and principle of block 201, reference can be made to description of block 101 in the above embodiment, which is not described herein.

At block 202, it is determined whether a preset key word is contained in the speech signal, if yes, the act at block 203 is executed, if no, the act at block 205 is executed.

At block 203, wake-up processing is performed on the smart device according to the key word.

At block 204, an operation state of the smart device is adjusted according to a control instruction contained in the speech signal.

In detail, the key word for waking up the smart device can be set in advance. If the speech signal contains the preset key word, the wake-up processing is performed on the smart device, and the operation state of the smart device is adjusted according to the control instruction contained in the speech signal.

There may be a plurality of preset key words, or may be one preset key word, which is not limited herein.

In an implementation, when the speech signal contains any of the preset key words, the wake-up processing is performed on the smart device, such that the operation state of the smart device can be adjusted according to the control instruction in the speech signal.

It should be noted that, in a possible implementation, after the wake-up processing is performed on the smart device according to the key word, if the speech signal containing the control instruction is not acquired, or the time period from when the speech signal containing the preset key word is acquired to when the speech signal containing the control instruction is too long, then the smart device is in the wake-up state for a long while, which may waste power.

In an embodiment of the present disclosure, the time period during which the smart device is in the wake-up state after being waken up is set as T in advance. After the smart device is waken up according to the key word contained in the speech signal, the smart device can be controlled to be in the wake-up state for the time period T. When the speech signal containing the control instruction is acquired during the time period T, the operation state of the smart device is adjusted according to the control instruction. When no speech signal containing the control instruction is acquired during the time period T, the smart device is controlled to enter an unawake state such as a dormant mode or a power saving mode, and when the smart device needs to be controlled, it is determined again whether the acquired speech signal contains the preset key word, so as to wake up the smart device again. In this way, the power consumption can be reduced.

For example, assuming that the preset key word for waking up the smart device is “xiaodu”, “xiao A”, and that the time period during which the smart device remains in the wake-up state after the smart device is waken up is one minute. When it is determined that the speech signal contains “xiaodu” after the speech recognition is performed on the speech signal acquired by the smart device, the wake-up processing is performed on the smart device. Then, if the control instruction “morning news” is acquired in one minute, the smart device is controlled to broadcast the morning news, if no control instruction is acquired in one minute, the smart device is controlled to enter the dormant state.

At block 205, a present operation scene of the smart device is determined, and a set of control instructions matching with the present operation scene is acquired.

At block 206, it is determined whether the control instruction corresponding to the speech signal matches with the present operation scene, if yes, the act at block 204 is performed, if no, the act at block 207 is performed.

At block 207, it is determined whether the control instruction collides with the present operation scene, if yes the act at block 208 is performed, if no, the act at block 209 is performed.

At block 208, the control instruction is discarded.

At block 209, the control instruction is executed.

Regarding the implementation and principle of blocks 204-209, reference can be made to description of blocks 101-102 in the above embodiment, which is not described herein.

With the method for controlling a smart device according to embodiments of the present disclosure, after the speech recognition is performed on the speech signal acquired by the smart device, it is determined whether the speech signal contains the preset key word, if yes, the wake-up processing is performed on the smart device according to the smart device and the operation state of the smart device is adjusted according to the control instruction contained in the speech signal, if no, the operation state of the smart device is controlled according to whether the control instruction corresponding to the speech signal matches with the present operation scene of the smart device and whether the control instruction collides with the present operation scene. In this way, the smart device can be controlled according to whether the speech signal contains the preset key word, such that the control method is simple and flexibility of the control method is improved, thus improving the user experience.
